Who Invented the Radio
Content
Who invented the radio? The credit of inventing the radio goes to a number of researchers. The names of Guglielmo Marconi, Nikola Tesla, Alexander Popov, Sir Oliver Lodge, Reginald Fessenden, Heinrich Hertz, Amos Dolbear, Mahlon Loomis, Nathan Stubblefield and James Clerk Maxwell can be included. Guglielmo Marconi He was an Italian inventor who demonstrated the practicability of radio communication. His first radio signal was sent and received in 1895. In 1899, the first wireless signal was sent across the English Channel. In 1902, the letter 'S' was telegraphed from England to Newfoundland. This was the first triumphant transatlantic radiotelegraph.
Nikola Tesla In 1892, he designed the fundamental design for radio. Later, in 1898, a radio controlled robot-boat was patented. This boat was controlled by radio waves and shown in the Electrical Exhibition in Madison Square Garden. This boat had an antenna that transmitted the radio waves arriving from the command post. A radio sensitive device called coherer received these radio waves. This device transmitted these waves to mechanical movements of the propellers on the boat.
Alexander Popov He constructed his first radio receiver containing a 'coherer' in 1894. This was then modified as a lightning detector and demonstrated before the Russian Physical and Chemical Society on May 7, 1895. This day is remembered by the Russian
Federation as "Radio Day". It was in March 1896, that transmission of radio waves was done across disparate campus buildings in St. Petersburg. A radio station was built on Hogland island to facilitate two-way communication by wireless telegraphy between the Russian naval base and the crew of the battleship General-Admiral Apraksin. This was done as per Popov's guidance in 1900.
Sir Oliver Lodge He designed a device called a 'coherer' upto perfection. This was a radio-wave detector and the basis of the early radiotelegraph receiver. He was showered with international recognition as he became the first human to transmit a radio signal.
Reginald Fessenden He was a Canadian inventor reputed for his achievements in early radio. The first audio transmission by radio in 1900, the first two-way transatlantic radio transmission in 1906 and the first radio broadcast of entertainment and music in 1906 were his three significant milestones. Fessenden concluded that he could devise a better system than the spark-gap transmitter and coherer-receiver combination that had been put forth by Lodge and Marconi.
Heinrich Hertz He was a German physicist and mechanician. In 1888, he became the first person to prove the presence of electromagnetic waves by constructing a system to create and detect UHF radio waves. His name was used for radio frequencies. The hertz designation was an official part of the international metric system in 1933.
Amos Dolbear He was a professor at Tufts University and received a U.S. patent for a wireless telegraph in March, 1882. Mahlon Loomis He is called as the "First Wireless Telegrapher". In 1868, he demonstrated a wireless communication system between two sites 14 to 18 miles apart.
Nathan Stubblefield It is thought that Stubblefield invented the radio before Tesla or Marconi. However, his devices appear to have worked by audio frequency induction or audio frequency earth conduction rather than radio frequency radiation for radio transmission telecommunication. It is claimed that he is the inventor of wireless telephony or wireless transmission of the human voice.
James Clerk Maxwell He predicted the existence of radio waves. It was on this basis that radio waves were discovered and Einstein's theory of relativity took off.
